Specification of Letters Patent.

Patented Oct. 31, 1 905.

Application filed April 3, 1905. Serial No. 253,645.

To all whont it may concern:

Be it known that I, GEORGE HUTOHINSON, a subject of His Majesty the King of Great Britain and Ireland, residing at Seatoun, Wellington, in the Provincial District of Wellington, in the Colony of New Zealand, have invented certain new and useful Improvements in Milking Machinery, of which the following is a specification- This invention relates to the milking-machine described in the specification accompanying my application for Letters Patent N o. 18 L216, dated the 7 thday of December, 1903.

The present invention provides improvements in the said machine consisting of the novel parts and the construction,arrangement, and combination of the same hereinafter fully described and illustrated, and as set forth in the claims.

My improvements are in connection with First. The'teat-presses. These stillhave the collapsible pouches surrounded by an inflexible outer wall, as described in my said previous specification, but the outer wall of the press is now in two parts, one part being hinged upon the other, whereby it may be turned downwardly to facilitate the placing of the teat between the pouches and to permit of the pouches being drawn out of the outer wall for cleaning purposes.

The pouches of my teat-presses are now constructed in the following manner: Two corresponding rubber frames have superposed sockets at each end. The upper sockets receive the upper or grip pouches, and the lower or follower pouches are formed by incasing each of the frames, thereby inclosing the grip-pouches. The two frames of a press are connected together at their forward ends. The two grip-pouches are connected by a bell-mouthed tube with the same fluidsupply pipe, and the two follower-pouches are also connected by a similar tube with another supply-pipe.

Second. Supporting the teat-presses. Instead of supporting the teat-presses from a cradle I now carry each press upon an independent arm, which is jointeol so as to be capable of movementin all directions. Means are provided for locking said arms when the presses have been adjusted.

Third. Apparatus for suspending the milking-gear and retaining it in position relatively to the animal. A bracket consisting of a bodybow and under arm for supporting the teatpresses and a spring-arm from which said bracket is suspended are still employed; but instead of causing said spring-arm to exert an upward pressure upon the udder I now take all pressure from the udder by interposing a belly-band, which comes into position upon the belly of the animal just in front of the udder. This arrangement also serves to prevent displacement of the gear in case of movement of the animal. The spring-arm is connected to a curved spring carried by a horizontal beam, the forward end of said beam being pivoted, whereby lateral adjustment can be made. Means are provided for readily adjusting the pressure of the spring arrangement.

Fourth. Apparatus for regulating the pressure in the teat-presses and for differentiating between the pressures in the upper or grip and the lower or follower pouches. Two pulsation-bags each operated upon by a rotating cam are placed upon independent air-cushions. Before commencing the milking operation air is pumped into the air-cushions until pressures are produced therein'corresponding to the pressures required in the teat-pouches, and when the pressures in the pulsation-bags rise to the desired limit the air-cushions yield and prevent excessive increase of pressure. I connect each air-cushion with an independent metal reservoir.

Fifth. Timing the pulsations in the pouches of the teat-presses. Means are provided for timing the pulsations in the upper and lower pouches relatively to each other by adjusting the space between each pulsation-bagand the lever which operates it. For this purpose I make the lever-arms in two parts and interpose a wedge between them, means being provided for adjusting the wedge and retaining it in position.

Sixth. Throwing the pulsation-gear in and out of action. The air-cushions referred to are carried upon a platform, which is hinged at one end, and means are provided for turning said platform upon said pivot toraise and lower the cushions with the pulsation-bags upon them, whereby they will be operated upon by the cams or otherwise. By this arrangement the cams may be continuously rotated while the pouches are upon the teats of the animal without pulsation being produced in the teat-presses until the moment desired. 7

The lever-arms, pulsation-bags, air-cushions, reservoirs, and air-pump for inflating the same are all carried upon a tray, which is independent of the cams and driving-gear, so that the pulsation-gear may be carried from stall to stall, an independent cam driving-gear being employed in each stall.

Seventh. Collecting the milk from a series of teat-presses. I use a chute which is adjustably mounted upon a jointed arm, giving freedom of movement in all directions. A swivel-jointed tube connects the chute with a receptacle, and means are provided for straining the milk and preventing splash.

I will now more particularly describe my improvements and the operation of the same by the aid of the accompanying drawings, wherein Figure 1 is a side elevation of a teat-press. Fig. 2 is a plan thereof; Fig. 3, a side elevation showing the teatpress open and the pouches drawn through for cleaning purposes.

Fig. 22 is a side perspective elevation of the bracket and suspension apparatus. Fig. 23 is an end elevation of the upper end of the body-bow and its bracket, and Fig. 2 1 a side elevation thereof. Fig. 25 is an end sectional elevation of part of the suspension apparatus. Fig. 26 is aside perspective elevation of a milk-collector,and Fig. 27 a plan thereof.

Referring more particularly to Figs. 1 to 3, the outer wall of the teat-press is made in two parts 1 and 2, the part 1 being secured to the part 2 by pivot-pins 3 and 1 opposite to each other in the opposing walls of the press, said pins passing through guide-slots 5 and 6 in the respective walls of the press, whereby the part 1 may be drawn out longitudinally from the part 2 and turned down into the position indicated in Fig. 3. The end of the part 1 has the hook 7, which receives the pin 8, projecting from the side of the part 2. To drop the part 1 into the position shown in Fig. 3,

it is first necessary to raise the end of part 1 until the hook clears the pin 8. Sockets 9 and 10, one above the other upon the front of the part 2, respectively receive the tubes 11 and 12 used for conveying fluid under pulsative pressure to the grip and follower pouches of the press. For strengthening purposes a metal plate 13 is carried across the top of the press at the front and atie-plate 14 connects the two Walls at the bottom of the press, and flutings 15 are provided in the part 1.

Referring now more particularly to Figs. 4 to 10, inclusive, in the construction of the teat pouches and nozzles for conducting fluid thereto I employ two corresponding frames each comprising a side piece 16. having upon its rear end an open ferrule 17 and a closed socket 18, and upon its forward end the ferrule 19, made integral with the ferrule 20, having the projecting spigot 21. The upper or grip pouch 22 is threaded through the ferrules 17 and 19 and its rear end is closed by a cap 23, which is secured within it. The lower or follower pouch 2 1 is formed by carryinga strip of flexible material around the frame, its side edges being secured to the sockets and ferrules and its ends being secured to the side piece 16. Each spigot 21 has a laterally-projecting boss 25, and the two frames of one set of pouches are connected by cementing together the two bosses, and to insure the bosses coming accurately together they are provided with male and female guides 26 and 27. The two grip pouches 22 of a press are connected by a U-pipe 28, the ends of which are secured within the open ends of the pouches. The U pipe has an opening 29, which is covered by a bell-mouthed pipe 30, which communicates with the feed supply pipe 11. The spigots 21 of the two frames are connected by a bell-mouthed tube 31, which is secured upon them and communicates with the feed-supply pipe 12. The side pieces 16 of the two frames (shown between the dotted lines in Fig. 5) may be dispensed with without impairing the utility of the parts which they connectviz., the front and rear parts of said frames, consisting of the ferrules and sockets.

The pouches are preferably made of fabric and unvulcanized india-rubber, and during the process of vulcanizing are retained in the position they will normally occupy when collapsed, the result being that they normally tend to lie closely against the sides of the rigid outer walls of the press, and dovetailed lugs 160 on the pouches, engaging in corresponding slots 161 in the part 2 of the teatpress, retain them in this position. When the pouches are withdrawn from the casing to the position shown in Fig. 3 the lugs readily leave the slots.

In order to enable the teat-presses to be adjusted to the positions of the teats of different animals, it is necessary that the means of supporting them should provide for the adjustment of the presses relatively to each other in all directions. For this purpose I connect each press by a ball-and-socket joint to the end of a lever pivotally connected to another lever, the upper end of which is journaled upon an under arm to be described.

Referring now to Figs. 11 to 15 inclusive, the spindle 32 is fixed in the brackets 33 and 34 by bolts 35, which pass through the following parts-via, the caps 36 of said brackets, the said spindle, the brackets, and the under arm 37, which projects from a body-bow hereinafter described. Upon this fixed spindle 32 are journaled four systems of levers each carrying one of the teat-presses. As these parts .are precisely similar it will be sufficient to describe one system. The upper lever 38 has a socket 39 upon its upper end, which is journaled on the spindle 32. A socket 40 upon the lower end of the upper lever receives a spindle 41, which has an integrally-formed jaw 42 projecting at right angles from it. The spindle 41 is held in the socket 40 by a washer 43, fixed upon its end by means of a screw 44. The sockets 39 and 40 are each divided by a saw-cut 45 and have the projecting ears 46 and 47, respectively. The bolt 62 passes through the ears and is sided at its upper end to fit within a recess formed in the ear 46. A wing-nut 63 screws upon the end of the bolt, and by screwing up said nut the ears are drawn toward each other, whereby the sockets 39 and 40 are simultaneously clamped upon the spindles within them. The jaw 42 upon the spindle 41 receives the end of the second lever 50, which is pivoted within said jaw upon a pin 51, a wing-nut 52 upon said pin being employed to lock the joint of the second lever by clamping the two parts of the jaw upon it. The teat-press is swiveled upon the end of the second lever in the following manner: A round spindle 53, having a flat side, fits telescopically within a hole in the end of the lever 50 and is secured therein bythe set-pins 54. A ball 55, integral with spindle 5.3, fits within and bears against the end of a socket 56, which receives a concave washer 57, bearing against the ball under pressure of a spring 58. The opposite end of the spring bears against the head 59 of a bolt 60, which passes through a square hole in a cover 61, said cover fitting tightly within the end of the socket 56 and being secured therein by bending over it the edge of the end of the socket.

The part 2 of the teat-press has a downwardly-projecting ear 58, through a square hole in which is passed the bolt 60, said bolt having a sided shoulder fitting said hole and also the hole in the cover 6]. A washer 61 is threaded upon the bolt and a nut 61 screwed up to clamp the ear between the washer and the end of the socket. The upper arm 38 has a projecting ear 64 to guide the bolt 62 and to prevent bending. Brackets 65 and 66, recessed to receive the lower feed-tubes, which convey fluid to the follower-pouches of the teat-presses, are formed integrally one with each of the outer jaws 42. A bridle 67, secured to each of said brackets, surrounds the upper and lower feed-tubes and retains them in position. The ends of the feed-tubes 11 conveying fluid to the grip-pouches are connected to a branch pipe 68, which is connected to a main feed-tube 69, leading to the pulsation-bag for these pouches. The ends of the feed-tubes 12 leading to the followerpouches are connected by a branch pipe with a main feed-tube 71, leading to the pulsation-bag for the follower-pouches of the teat-presses.

Referring now to Figs. 22 to 25, inclusive, the teat-presses are supported from overhead in the following manner: The under arm 37 projects approximately horizontally from a body-bow 72, which is curved to clear the side of the animal. The bracket 73 at the bottom of the body-bow has a rectangular socket 74, in which the end of the underarm is removably fitted. Upon the upper end of the body-bow is fixed a bracket 75, having ears 76 journaled upon a bolt 77, carried in ears 78,integral with a socket 79, whereby the bodybow is free to swing longitudinally with the animal. The socket 79 slides and turns upon the cylindrical end of a pole 80, which is of ash or other springy material, and is clamped at its forward end to a curved spring 81. The opposite end of the spring is carried in a fork 82, formed at the end of a lever 83, passing through a beam 86. The opposite end of the lever 83 is adapted to engage in one or other of a number of notches 87, formed in a bracket 88, which is secured to and projects downwardly from the beam 86 and has a foot 89, which limits the upward movement of the pole 80. A handle 90 is made upon the end of the lever 83, and a stop 91, projecting upwardly therefrom, prevents the hand of the operator from being caught between the handle and the beam when adjusting the end of the lever in the notches of the rack referred to. The beam 86 is pivoted at its forward end in a fixed cross-rail 92 and at its rear end has a metal loop 93, which receives another fixed cross-rail .94. By this arrangement the beam can be turned upon its pivot 95 to bring the teat-presses out of the way of a cow entering or leaving the milking-stall and then can be brought back immediately over the spine of the next animal. The socket 79 can be moved along the pole to suit the length of the cows body and allows the apparatus to swing laterally in case of movement of the animal.

Referring again to Figs. 11, 12, 13, and 22, to prevent displacement of the gear from the animal consequent upon her movements I employ a leather bell y-band 96, which is secured at its ends by the lace 97 to wire brackets 98 &

and 99 and to the intermediate eyes 100 and 101, fixed to the under arm. This belly-band bears against the animal just in front of the udder and is held in position by the upward pressure of the spring arrangement used for supporting the milking and milk-conducting gear. The wire bracket 99 is extended downwardly, forming a guard 102 to protect the jointed arms. Clamps 103 and 104 secure the brackets 98 and 99 with the guard 102 to the under arm 37. A pad 105 is fixed near the middle of the belly-band, where it will occupy a position between the lobes of the udder and help to prevent lateral displacement of the gear and also reduce pressure of the belly-band upon the veins of the animal.

Apparatus for producing intermittent pressure in the teat-pouches is constructed as follows, referring to Figs. 16 to 19, inclusive: The shaft 106 is carried in the bearings 107, fixed to the foundation-frame 108, and carries cams 109 and 110, the fly-wheel 111, and the pulley 112, by which said shaft is revolved from any convenient source of power. The cams 109 and 110 are adapted to engage, respectively, with friction-rollers 113 and 114, which are respectively journaled upon the ends of the levers 115 and 116, said levers being respectively fixed at their ends in brackets 117 and 118, pivoted upon a rod 119, fixed in the brackets 120 and 121, projecting upwardly from a tray 122. Beneath the lever 115 is arrangeda cylindrical pulsation-bag 123, communicating through the main feed-tube 69 with the branch pipe 68, which has four branches each, as previously described, having a tube 11 connecting it with the grip-pouches of one teat-press, there being one pulsationbag for all the upper pouches in a series of presses for milking one animal. Beneath the lever 116 is arranged a similar pulsation-bag 124, communicating through the main feedtube 71 with the branch pipe 70, having four branches, each having a pipe 12 connecting it with thefollower-pouches of one of the teatpresses, there being one pulsation-bag for all the follower-pouches in a series of presses for milking one animal. For the purpose hereinafter described battens and 126 are employed beneath the respective levers115 and 116. Disk-shaped pressure-blocks 127 and 128 are fixed beneath the respective ends of the battens 125 and 126. The pulsation-bag 123 rests upon an air-cushion 129, which is in communication through a pipe 130 with a metal cylindrical air-reservoir 131, fitted with a pressure-gage 132, and a blow-off cock 133. The pulsation-bag 124 rests upon an air-cushion 134 and is in communication through a pipe 135 with a reservoir 136, similar to reservoir 131 and having a pressure-gage 137 and a blow-off cock 138. An air-pump 139 of ordinary construction is used to force air into both the reservoirs through branch pipes 140 and 141, a two-way cock 142 being employed to open communication between the pump and one or other of the reservoirs, as desired, through non-return valves of well-known construction 143 and 144. internal vertical tie-walls 145. These are for the purpose of preventing the upward expansion of the cushions beyond a predetermined limit. Without an arrangement of this sort the upward expansion of the air-cushions folof the cam by coil-compression springs 146 and 147, which are interposed between the under sides of the levers and the bottom of the tray 122. Thongs 148 and 149 of leather or the like connect the levers with the bottom of the tray 122 and prevent the levers from rising more than is required.

The air-cushions have To insure effective milking, it is necessary that the upper or grip pouches of a teat-press squeeze the upper part of the teat in advance of the lower or follower pouches, which are used to squeeze out the milk from the teat. To obtain this result, I employ the battens 125 and 126, one beneath each of the levers 115 and 116, as hereinbefore indicated, and interpose the wedge 150 between the lever 115 and batten 125 and the wedge 151 between the lever-116 and the batten 126. The battens are respectively pivoted at their rear ends upon the pins 152 and 153 in the brackets 117 and 118. The adjustment of one of the wedges between its lever and batten brings the pressure-block 127 or 128, carried by the batten, closer to or farther away from its cam, with the result thatthe pressure-block comes into action upon the pulsation-bag sooner or later, as the case may be. Each wedge has a rearwardly-extending rod 154, having an upward extension provided with a looped handle 155. This looped handle engages in one or other of the notches of a notched bracket 156, secured upon the top of the lever to hold the wedge after adjustment. Plates 162, secured to the battens, form channels to guide the wedges. If the pulsation-pouches are charged in the proper relative proportions in the first instance, no adjustment of the wedges is necessary; but they are useful when the charging of the pouches is not done with accuracy. The handle 157 is secured to the tray for convenience in carrying it about.

In practice it is advisable to run the camshaft continually and to commence the milking operation very gradually. To effect this, the pulsation-bags and their levers are lowered until they are out of reach of the throw of the cams in the following manner: The

' off the slide-piece 165.

I tray 1252 rests upon the platform 158, which taps 181 and 182, to which flexible tubing may be connected, having funnels at their upper ends for the purpose of supplying liquid to the pulsation-bags from some height above them, so that air does not pass into the bags with the liquid.

Referring now more particularly to Figs. 20, 21, 26, and 27, the milk is collected from the four teat-presses comprising a milking set in a vessel 163, having a rectangular socket 164: fitting over a slide-piece 165, pivoted to move in a vertical longitudinal plane upon the jointing-piece 166. Thejointing-piece is pivoted to move in a horizontal plane upon the arm 167, the opposite end of which is also horizontally pivoted to a jointing-piece 168, which is pivoted to move in a vertical longitudinal plane upon the end of the arm 169. which is journaled in a bracket 170, fixed to the under arm 37. This arrangement permits of the vessel 163 being moved vertically and horizontally to suit different animals. The vessel is removed by sliding the socket 164: The bottom of the vessel 163 inclines toward a discharge-tube 171, the end 17 2 of which is spherical and fits freely within the upper end of a tapering tube 173, having hinged upon it a wire loop 174:, which takes over a hook 175 upon the end of tube 171.

To prevent splash of the milk falling into the vessel 163, I employ an apron 176 of fabric, such as flannellet, which fits over the top edges of the walls of the vessel. An upwardly-projecting wire frame 177 is fixed upon the bottom of the vessel and raises the middle of the fabric, and a Wire bow 178, serving as a weight, rests upon the fabric upon each side of the frame and causes it to hang in a series of inclined planes, against which the milk impinges.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1.
